Yes makes sense. This can be replaced during merge I guess.
-?????? tst_cmd(argv, "/dev/null", NULL, 0);
+?????? SAFE_CMD(argv, "/dev/null", NULL);

Honestly I hate implicitness like that. I think if the test itself needs 
the tmpdir, it should state it and not rely on some other "needs_*" 
stuff to also enable it.
But if whoever merges this agrees with you, he can change it...
